See attachment for complete question
Solving (a): Area of Orchid Hill (in square miles)
The dimension of the neighborhood is 4 blocks by 3 blocks
Since each block are of the same dimensions
The area is calculated as:
[tex]Area = 4blocks * 3 blocks[/tex]
If [tex]20\ blocks = 1\ mile[/tex] then:
[tex]1\ block = \frac{1}{20} mile[/tex]
[tex]1\ block = 0.05mile[/tex]
So, we have:
[tex]Area = 4blocks * 3 blocks[/tex]
[tex]Area = 4 * 0.05 * 3 * 0.05[/tex]
[tex]Area = 0.03mi^2[/tex]
Solving (b): The population density of the neighborhood as people per square mile
From the question, we have:
[tex]People = 360[/tex]
[tex]Area = 0.03mi^2[/tex] --- calculated
So, the population density is:
[tex]Density = \frac{People}{Density}[/tex]
[tex]Density = \frac{360}{0.03}[/tex]
[tex]Density = 12000[/tex]

Answer:
Middle answer is right
Step-by-step explanation:
The first answer is obliviously wrong so therefore it is the last two options
-(x+1)^2
= -(x^2+2x+1)
= -x^2-2x-1-3 (add the -3)
= x^2-2x-4
y intercept make x=0 therefore y=-4
AOS is x= -b/2a
x=2/2 which is 1
therefore it isthe middle answer
What is the Y-intercept of the simplified equation??
Answer: -7
Step-by-step explanation: y+3x=8x-7
subtract 3x from both sides y=5x-7
y=Mx+b
b=-7
Evaluate the function.
f(x)= - x^2 - 10x
find f(-5)
Answer:
f(- 5) = 25
Step-by-step explanation:
To evaluate f(- 5) , substitute x = - 5 into f(x) , that is
f(- 5) = - (- 5)² - 10(- 5) = - 25 + 50 = 25

Step-by-step explanation:
The function f(x)=240x represents the cost of staying at a particular hotel for x nights at the full room rate of $240 per night. The hotel gives its rewards members a discount based on the length of their stay. Each additional night that rewards members stay earns them an additional 5% discount on the total cost of their stay up to a 30% discount. The function d(x)=0.05(x-1) for 1 < x ≤ 7 represents the percentage discount in decimal form for a rewards member staying x nights at the hotel.

A customer earns 1 free night per 10 nights stayed.
What is function?Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable.
Here, we have,
A hotel offers a reward program based on the number of nights stayed. The function f(x) represents the number of free nights earned as a function of x, the number of nights stayed.
f(x)=x/10
When we put x=10, we get f(1)=10/10=1
Here f(1) represents the number of free nights earned by the customer is 1 per 10 nights stayed.
When we put x=20, we get f(2)=20/10=2
Here f(2) represents the number of free nights earned by the customer is 2 per 20 nights stayed.
When we put x=30, we get f(3)=30/10=3
Here f(3) represents the number of free nights earned by the customer is 3 per 30 nights stayed.
When we put x=40, we get f(4)=40/10=4
Here f(4) represents the number of free nights earned by the customer is 4 per 40 nights stayed.
Then, the pattern permits you to conclude that a customer earns 1 free night for every 10 nights stayed.

Step-by-step explanation:
Let label this using a triangle.
We are sitting 300 ft away from the building.
We can look up to see the top of building at an angle of 60 degrees. So 60 degrees would be near where we standing at. The other angle of the top triangle would be 30 since that the height of building and the ground horizon is perpendicular to each other so they measure 90 degrees. Using triangle interior theorem, the missing angle would be 30.
We use another triangle since we are looking down.
The height of building and where we sitting at is perpendicular. The angle near we at would measure 15 and the missing angle would be 75.
The triangles both combine to form one triangle. They would form a isoceles triangle.
The most bottom angle of the triangles measure 75 while the angle where we are at of both triangle measure 75. so we have a isoceles triangle.
This means that the hypotenuse of the top triangle is equal to the length of the building.
To find the hypotenuse use 30-60-90 rules,
hypotenuse =twice of most shortest side.
[tex]h = 300 \times 2[/tex]
[tex]h = 600[/tex]
So the length of the building is 600.
3 squares are positioned to form a triangle. The small square is labeled 6 units, medium square is 8 units, and large square is not labeled.
Answer these questions about the right triangle.
What is the area of the square of the leg 6?
✔ 36 square units
What is the area of the square of the leg 8?
✔ 64 square units
What is the area of the hypotenuse square?
✔ 100 square units
What is the length of the hypotenuse?
✔ 10 units
Answer:
Area of Square(leg 6): 36units
Area of square(leg 8): 64units
(3) 100units is the Area
(4) Length of hypotenuse is 10units
Step-by-step explanation:
Square(leg 6): 6*6= 36
Square(leg 8): 8*8=64
The bigger square: 64+36=100
The length of the hypotenuse is 10units because 10*10=100

In general, describe how the outcome of the hypothesis test changes as the level of significance decreases.
Answer:
The region of acceptance gets bigger and the null hypothesis is mostly accepted as it lies in the acceptance region.
Step-by-step explanation:
As the level of significance is decreased the area for the favorable outcomes is increased. The value of ∝= 0.1 has a narrower area of favorable outcomes then the values of ∝= 0.05 or 0.01 because the value 0.1 ( 1%) is closer to the middle value or at the extreme values of the distribution as the case may be for 2 tailed or 1 tailed test.
Significance level Two tailed Test One tailed test
0.1 ± 1.645 ±1.28
0.05 ±1.96 ± 1.645
0.01 ± 2.58 ± 2.33
So if the middle point is taken as zero we see that the spread of the area of the favorable values increases as the value of ∝ significance level decreases.
The region of acceptance gets bigger and the null hypothesis is mostly accepted as it lies in the acceptance region.

Kit charges customers an initial fee plus a certain amount per hour to walk their pets. The table below shows the amount of money that Kit earns at her job based on the number of hours that she works. Which of the following equations represents a scenario where Kit would charge customers a higher rate to walk their pets than what is shown in the table?
Answer:
The answer would be 7.5
Step-by-step explanation:
This is due to if there were to be a chart it would start at 15 then continue by 7.5 which would then lead to 1 hour which is 22.5 min additionally other people are not answering this because you did not give all the information such as the chart etc and the answers unlike me i have the toolds and the questions.
The equation y = 8x+10 represents a scenario where Kit is charged a higher hourly rate to walk their pets.
What is a linear equation?It is defined as the relation between two variables if we plot the graph of the linear equation we will get a straight line.
If in the linear equation one variable is present then the equation is known as the linear equation in one variable.
As per the table:
When the hours are 0 earnings are $15
Initial fee = $15
And when hours are 1 earnings is 22.5
∴ $22.5 = initial fee + hourly rate
Hourly rate to walk their pets = 22.5 - 15 = $7.5
So from the equation:
y = 7.25x + 20
Here 7.25 is the hourly rate to walk their pets and 20 represents the initial cost.
After observing all the equations:
In the equations:
y = 8x + 10
The hourly rate to walk their pets is 8 and the initial cost is $10 in this case Kit is charged a higher hourly rate.
Thus, the equation y = 8x+10 represents a scenario where Kit is charged a higher hourly rate to walk their pets.

Answer:
Circumference = 62.8
Step-by-step explanation:
The equation for discovering a circle's circumference is simple:
-------------------------------------------------------
C = 2πr
C is the circumference (how long is the circle around)
R is the radius (half of the width of the circle)
--------------------------------------------------------
So, instead of giving us the radius, they gave us the diameter. (the full width of the circle) So, we divide that by 2 to get the radius.
20/2=10
Now, time to fill in the equation.
C = 2π10
C = 20π
C = 62.8
*They told us to use 3.14 for pi.
